I haven't managed to mix up my tobacco e juices yet because I haven't found the label maker yet. And to be honest the coffee kind of scares me. Scent memory is a powerful thing. But hopefully I'll have time and energy for this in the next few days when I have break. Then I just have to grow a pair and try the coffee. My sister insists it does smell like coffee now, but I am afraid it will always smell like death to me.
